If R600 could do DX10.1 wouldn't ATI have enabled it with drivers? That should answer question 1.
Even if it could, looking at Taltamir's timeline, R600 was released 7 months after Vista was released. So a big bullet point of Vista would be unsupported in hardware for at least 7 months (if r600 support DX10.1 that is) or up to 13 months (if R600 doesn't support DX10.1) if DX10 wasn't shipped in it current form.
